Z-one (center bottom) with (from left to right) "Gabrion", "Metaion", "Sephylon", "Zadion" and "Sandaion".
"Timelord", known as "Temporal Machine God" (
"Necrolancer the Timelord" is excluded from this archetype, since its Japanese name does not contain the appropriate kanji.
The "Timelords" are Level 10 Fairy-Type monsters of various Attributes (except DARK) with 0 ATK (except for "Sandaion, the Timelord" and "Sephylon, the Ultimate Timelord") and 0 DEF (except "Sandaion" in the anime and "Sephylon", who has 4000 DEF). The "Timelords", except "Sephylon", share some effects: they can't be destroyed by battle or by card effects, and reduce the Battle Damage from battling to 0 while in Attack Position. They all share two other effects: The controller cannot Summon other monsters (exclusive to the anime), and they return to the owner's Deck during their Standby Phase, except for "Gabrion". They can all be Normal Summoned without Tribute if one controls no monsters, though that effect is not present in the anime.
In addition to sharing those effects, the "Timelords" have a separate effect that activates when they battle in the anime. In the TCG and Yu-Gi-Oh! 5D's Tag Force 6, these effects trigger at the end of the Battle Phase instead (except "Raphion, the Timelord", who is still trigger it's effect when it battled a monster after the damage calculation). These effects either involve bouncing cards to the hand or Deck and/or dealing Effect Damage to the opponent:
- "Metaion" returns all other monsters on the field to the hand whenever it battles, and inflicts 300 damage per monster to the opponent.
- "Razion" returns all monsters the opponent controls and all cards in the opponent's Graveyard to their Deck when it battles, and inflicts 1000 damage to the opponent when they draw a card during the Draw Phases; in Tag Force 6, "Razion" only returns the opponent's Graveyard to the Deck, and deals 500 damage to the opponent every time they draws a card(s).
- "Tzaphion" returns all Spells and Traps the opponent controls to their Deck when it battles. Additionally, when it leaves the field and returns into the Deck, its controller draws cards until they have 5 cards in their hand; The draw effect is removed in Tag Force 6.
- "Zadion" changes the controller's Life Points to 4000 when it battles, if their Life Points were less than 4000.
- "Camion" returns all monsters the opponent controls to their Deck when it battles, and inflicts 500 points of damage per monster; In Tag Force 6, "Camion" only returns one face-up monster to the Deck and then deals 500 damage.
- "Raphion" returns the monster it battled to the owner's hand and inflicts damage to your opponent equal to that monster's ATK; "Raphion's" effect is altered in Tag Force 6 with the effect that returns a monster to the hand removed.
- "Hairon" inflicts damage to your opponent equal to the difference between you and your opponent's Life Points; This effect only activates when your Life Points are lower in Tag Force 6
- "Michion" halves your opponent's Life Points when it battles.
- "Gabrion" returns all cards your opponent controls to their owner's Deck; "Gabrion" only returns 1 card to the Deck in Tag Force 6.
- "Sandaion" inflicts 4000 damage to the opponent when it battles; in Tag Force 6, "Sandaion" can't deal Battle Damage and the effect damage is only 2000.
So far, the only "Timelords" released in the OCG are "Metaion" and "Sephylon".
Each of the "Timelords" reflect a part of the Sephirot, as well as one of the archangels (except "Sephylon", which is based on the mystical state Da'at, the divine light, where all Sephirot become one).
However, when all of the cards appear in the Tree of Life (as seen in the anime, shown right is an edited version), "Michion" and "Raphion" are in each others' places.
Even though they can't be destroyed, they are not invincible, for they can still be removed from the field by other means. Additionally, If a "Timelord's" effects are negated, it becomes more of a liability then anything else because of its 0 ATK (except for "Sephylon" and "Sandaion"). Cards that remove them from the field are considered very useful against "Timelords" (although bouncing them back into the hand isn't exactly the best idea).
Their high Levels can also be exploited with cards such as "Level Limit - Area B" and "Gravity Bind". Besides, the fact that the player who uses Timelords will only have 1 Timelord at a time in the field makes cards like "Scrap-Iron Scarecrow" and "Hook the Hidden Knight" render them useless, since once they cannot successfully attack, their effects will not activate.
Also, Cards like "Lava Golem" or "Volcanic Queen" will Tribute the "Timelords" and Summon themselves to the "Timelord's" controller's field without destroying them, blocking the field and stopping their controller to Summon any other "Timelords".
- In the anime, all the Timelords have a Rare rarity with exception of "Sephylon, the Ultimate Timelord", which has an Ultra Rare rarity instead.
